I have replaced the headlights relay, the fuses, checked the bulbs, and inspected the blinker switch not a blinker switch expert, but it looked okay. I really don't want to have to take this to a shop. Ideas?

Hi,just food for thought,when you switched the lights on did you check if there is aney power to the lights with ignition on,I thought that then atleast you would know that its not before the lights if there is power there.all the best,hope you get it sorted out.

Well, currently I'm trying to determine where to go to get this checked. I don't have equipment to do so, and I'd rather not spend 100 dollars somewhere for someone to hook up an electrical tester.Well, currently I'm trying to determine where to go to get this checked.

My 02 Dodge Ram 2500 also had this issue however mine was in need of a positive ground. Yours may be just a regular ground,Try running a ground wire to the battery from the wiring harness.

Could your Mazda have daytime running lights? If you checked all fuses, did that include the three in the joint box?

There is an auto light-off control module that is central to all functions you describe. It is assumed that you would only turn on the fog lights with headlights on and set for high beam. If you set the headlight switch to LOW, the module closes the headlight relay to turn on the low beams. If you then turn the headlight switch to HIGH, the module turns on the high beams and allows you to turn on the FOG LIGHT switch, closing the fog light relay and turning on the fog lights. Since this sequence is not working, I suggest checking both high beam lamps as both could be burned out. Other possibilities are a defective headlight switch or the module

[Information] For a 2002 Toyota Camry, the Daytime
Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to
the center of the vehicle front) at a reduced power.

[The troubleshooting process:] Review the Owner's Manual and ensure the test
configuration matches the following criteria:
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness
when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."

2. Set the Test Conditions according to Step 1 above.

3. Check the headlight bulbs to ensure they are not
burned out. If one burns out, there is a fair chance that the other would have burned
out at the same time. Replace as necessary.In this case, if the high beams operate, the DRLs should also operate.
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function
Switch on Turn Signals in "DRL" position, headlight switch off
(repeating what the manual says -- it should be obvious that in the
"DRL" position, the headlight switch should be off / do not have the
switch positioned to "High Beam"), and the Parking Brake
"off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box.
there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3).
Any one of them could be bad (stuck or burned out). Test (step 4).
7.Other less likely possible issues
could be that the Multi-function Switch is broken or a connection / wire is
broken.[Beyond the scope of this
process.]

My problem was that the test configuration did not have
the engine running and parking brake off - Step 1. Problem solved with much
thought, repetitive tests on the vehicle and going back to the basics -- what
does the Owner's Manual say and where are the applicable fuses and relays
located?

If high beams work and low beams do not, then it is probably the high/low relay. It is part number 15016745 and has four prongs. To test if your relay
has gone bad locate the relay in your fuse box. There will be two of these
relays located next to each other. One controls the low beam headlights
and the other the cooling fan. Swap the relays and check your low beam
headlights. If the low beams work you have a bad relay.

could be bad bulb or while you were changing plug wires you disturbed the headlight wiring.check grounds,try moving the head light wires around to see if bad connection.if pass sides working it shouldnt be fuse or switches.
